ON AN ill-fated day in March 2017, James Johnson crashed while para-motoring, a sport that involves strapping a propeller and parachute to a go-kart and flying over 3 000 metres in the air. When he woke up in a hospital, he thought his life was over. The nurse and father of four had broken his neck, leaving him quadriplegic. He would never walk again, he was told.

James is one of about three dozen people in the world fitted with what is known as a brain-computer interface (BCI), an array of electrodes implanted in the brain and connected to a computer that interprets thoughts and translates them into actions on electrical devices.
The technology gives him a power akin to telepathy and telekinesis. The one rather obvious clue of that superhuman capability is the screw-on bolts protruding from his skull. These cover sockets connect to cables that send his brain activity to computers, enabling him to make art, write emails and even play video games with the power of thought alone.
James is a pioneer in an industry that is quietly booming.
At least half a dozen start-ups are developing BCIs, or neural
